Sebastian Andrzej Siewior 466e88548e bnxt_en: Flush XDP for bnxt_poll_nitroa0()'s NAPI

[ Upstream commit edc0140cc3 ]

bnxt_poll_nitroa0() invokes bnxt_rx_pkt() which can run a XDP program
which in turn can return XDP_REDIRECT. bnxt_rx_pkt() is also used by
__bnxt_poll_work() which flushes (xdp_do_flush()) the packets after each
round. bnxt_poll_nitroa0() lacks this feature.
xdp_do_flush() should be invoked before leaving the NAPI callback.

Invoke xdp_do_flush() after a redirect in bnxt_poll_nitroa0() NAPI.
